Assessment of a threatened species Ulmus minor in north-western Tunisia

Santrauka The status of Ulmus minor Mill., a threatened species in Tunisia, was assessed. The study aimed to determine the habitat conditions and gather ecological information about the species and its habitats in north-western Tunisia since the lack of data on the abundance and distribution of this species is a significant obstacle to its proper conservation. The results revealed that the species is currently distributed in Tunisia in two localities (Oued El Kebir in Tabarka and Tbeinia in Ain Draham). The populations occur in deep, very wet, loamy or clay loam soils of low acidity. The main threats to the species are overexploitation by local people and disease caused by the ascomycete Ophiostoma novo-ulmi. Conservation of Ulmus minor can only be achieved through habitat maintenance and sustainable use of natural resources
